1 Claim. 1

My invention, which relates generally to the art of refrigeration,particularly has for its objects:

1. To provide an improved cooling-coil-plate of such construction as topresent a maximum cooling surface in a plate of a given length andbreadth.

2. To provide an improved cooling-coil-plate which can be manufacturedat a minimum cost.

3. To provide an improved cooling-coil-plate of any desired size for useeither as the side and end walls of a refrigerator can such as is usedin low temperature refrigeration, or as shelfplates in refrigeratorsgenerally.

Other objects will in part be obvious and in part be pointed outhereinafter.

To the attainment of the aforesaid objects and ends, invention furtherresides in the novel details of construction, combinations andarrangements of parts all of which will be first described in detail andthen be specifically pointed out in the appended claims, reference beinghad to the accompanying drawings in which:

Fig. 1 is a face view of a cooling-coil-plate embodying my invention.

Fig. 2 is an enlarged detail section of the same on the line 2-2 of Fig.1.

Fig. 3 is a face View of a cooling-coil-plate designed for use as ashelf.

Fig. 4 is a detail face view (parts being broken away) of a modi-cationof the shelf of Fig. 3.

Fig. 5 is an enlarged end elevation of the structure shown in Fig. 4.

Fig. 6 is an enlarged detail section on the line S-I of Fig. 4.

Fig. 7 is a schematic plan view of four of the plates of Fig. 1 arrangedas the four sides of a can.

Fig. 8 is a schematic perspective view of the four sides assembled witha -bottom plate and a top flange.

In the accompanying drawings in which like numbers and letters ofreference indicate like parts in all the gures, I represents the facesheet and Ia the back sheet of a cooling-coil-plate. The sheets areembossed to provide a plurality of parallel rows of series of embossings2, 2a respectively, one row of a series of embossings 3, 3arespectively, and an inlet 4 and outlet 4a (Figs. 1 and 2).

The embossings 2, 2a, 3, 3a are all of the same length. The embossings3, 3B respectively, lie in a direction at right angles to the directionof the embossings 2, 2a respectively.

The distance between the outer side edges of any two rows of embossings2 or 2a is equal to the end to end measurement of one of the embossings3 or 3a and the space between any two embossings is the same.

Thus it will be seen that when a front sheet I and a back sheet Ia areassembled with the inlet 4 and outlet 4a diagonally opposite there willbe formed a continuous zig-Zag passage for cooling fluid from inlet 4 tooutlet lia. After placing the sheets together they are seam welded(indicated by the black dots w in the drawings) along the marginalportions and between the rows of embossings.

When embodied in shelving, the parallel rows of embossings 2X, 23X (Fig.3) or 2W, Elay (Fig.` 4) preferably run lengthwise of the sheets insteadof 4crosswise of the same as in Fig. l.

Instead of having the inlet and outlet opening normal to the plane ofthe plate, they may be formed to open edgewise of the same as shown atIIay and IIY in Figs. 4 and 5.

Plates I may be secured together as indicated in Fig. 7 to form the foursides of a can by bending the ends, as at I, and welding them together.

Pipes Id connect the outlet of one plate to the inlet of the nextadjacent plate of the sides (see Figs. 7 and 8).

After assembling the four side plates I--Ia a top flange Ib and a bottomplate Ie are welded to the plates I--Iag as indicated in Fig. 8, tocomplete the can. The can is then placed in a suitably insulated box ina manner well known and forming no part of my present invention.

All embossings being of the same length (except the inlet and outletones) and being equally spaced apart as above described, the front andback sheets of metal can be embossed by a single set of dies such asthat which comprises the subject matter of my co-pending application ledJuly 19, 1946, Serial Number 684,967.

From the foregoing description taken in connection with the accompanyingdrawings it is thought that the construction, uses and advantages of theinvention will be clear to those skilled in the art.

What I claim is:

A cooling-coil-plate formed of two metal sheets placed in face to facecontact and having outwardly extended parallel rows of elongatedembossments, the embossments of one sheet being staggered with respectto and overlapping the embossments of the other sheet to providecontinuous-flow passages from first one inner face of the sheet and thento the inner face of the other sheet, each sheet having a row ofelongated embossments along one side for connecting alternate rows ofthe rst mentioned embossments at opposite sides of the plate therebyforming a continuous-fluid passage from an entrance adjacent one cornerof the plate to an exit adjacent the diagonally opposite cornen` of thesame said passage zig-zagging from one side of the plate to the oppositeside and from front face to back face of the plate.
